I didn't have any leaks when I switched to synth, don't want to test fate

2) "Jets"..they spray fuel or oil into cylinder?


3) Is this much different than Seafoam or Lucas and what they claim with those products? Although I know you only use Seafoam periodically, not at every fill up, and you don't leave it in the oil long term either IIRC when I used it.
Well! That's why Mobil 1 invented their high mileage version (75K+). I had leaks too until I switched to this version that contains a seal improving ingredient. This type of seal technology is available by itself, but Mobil 1 does it in one convenient package. I've noticed no leaking since introducing Marvel Mystery. I'm now at 750 miles and am using less than half the oil I'd expect. I'll keep you posted.
